Application May 16, 1938, Serial No. 208,286

1 Claim.

This invention relates to a valve keeper remover, the general object ofthe invention being to provide a device for depressing the springs ofvalves of a motor and holding the springs depressed while the keepersare being removed, so that the valve assemblies can be removed forgrinding and other purposes, the invention also being used in replacingthe valves by holding the springs depressed while the keepers are beingput in place.

The invention also consists in certain other features of construction,combination and arrangement of the several parts, to be hereinafterfully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claim.

In describing the invention in detail reference will be had to theaccompanying drawing Wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Fig. l is a fragmentary sectional view through a part of a motor showingthe invention as used in holding the valves depressed, the keepers 5having been removed.

Fig. 2 is a top plan view of Fig. 1.

Fig. 3 is a sectional view of the valve keeper remover.

Fig. 4 is a perspective view looking towards the under side of thedevice.

Fig. 5 is a detail view showing the keepers in place on a valve stem,the keepers being shown in section.

As shown in this drawing, the device is composed of a plate-like memberI having a pair of holes 2 therein which are spaced apart a suificientdistance to receive a pair of valve stems 3 of the valve arrangement ofa motor. A circular recess 4 surrounds each hole on, the bottom of themember for receiving the upper spring seat 5. A recess 6 surrounds eachhole on the upper face of the member, thus recess curving downwardlyfrom the top face of the member to the hole as shown. These recesses 6enables the keepers l to be readily removed from the annular groove 6 inthe upper end of each stem, it being understood that the reduced partformed by the groove, tapers downwardly and that the keepers aresimilarly formed and that the keepers act to hold the spring seat inplace at the upper end of the stem.

A tubular part 9 extends downwardly from the member I in rear of theholes and in a plane passing between the holes and a hole It] passes 55through the member and registers with the bore of the tubular member sothat a head bolt ll of the motor can pass through. Thus the member orpart 9 spaces the device from the motor head and by tightening the nut62 of the bolt the member i will be caused to compress the springs 5 I3, as shown in Fig. 1, so that the keepers can be removed or replaced.

Thus it will be seen, that after the motor head has been removed, thedevice is placed on one of the head bolts with the recesses 4 fittingover 0 the seats of the springs with the stems passing through the holes2. Then the nut i2 is placed on the bolt and tightened to cause themember l to compress the springs and then the keepers can be removed bythe fingers. After the kee-p- 15 ers of one pair of valves are removedthe device can be placed on another belt and another pair of keepersremoved.

With this invention the springs can be easily and quickly depressed toenable the keepers to 20 be removed or replaced.

It is thought from the foregoing description that the advantages andnovel features of the invention Will be readily apparent.

It is to be understood that changes may be 25 made in the construction,combination and arrangement of the several parts, provided such changesfall within the scope of the appended claim.

What we claim and desire to protect by Letters 3 Patent is:

A valve spring compressor adapted for use on motors which have a pair ofvalves located adjacent a head stud bolt, said compressor comprising apiece of inflexible metal of substan- 5 tially triangular configurationhaving a tubular part extending from one side thereof adjacent the apexof the triangle the bore of the tubular part being of such size as toclosely embrace a head stud bolt and guide the compressor as it 40 isactuated by a nut associated with the stud bolt and companion aperturesformed therein adjacent the base of the triangle to receive the valvestems of a motor, each aperture merging into an enlarged countersunkrecess on that side of the compressor carrying the tubular part toreceive the ends of the springs to be compressed, and each aperture onthe opposite side of the compressor merging into cup-shaped recesses inthe opposite surface of the compressor to facilitate the removal ofvalve keepers.
